I can use Photoshop to concept and texture but the 3d stuff i'd do in a proper 3d package.
You can get some average photo based normal maps with either xnormal or nvidia plugin for photoshop but it never compared to actually sculpting detail.

Well if you have the original textures you can use them as guides to show you where the uvs "which is the texture space coordinates" are, then all you have to do is paint over them or replace them completely.

The reason it wraps around the other side is due to the uv space coordinates being overlapped, its a common technique to get the most out of your uv space so things will be higher resolution.

Apart from that I have not got much idea how quake character models work (hierarchy etc), I've heard they can be fairly complex. (for quake that is)

I assume you have this texture?.... (dont use the jpeg) (use your .tga version) see attached.... when you have edited it make sure you save it as a 32bit tga to keep its alpha channel. You can find the model and its textures in PAK0. You might have to make her as a copy of herself to re-skin her but as i said ive never worked with quake chars before.

robbing a bank with crash mask would be awesome

i think you have a crush on crash (oh what a lame, at least unintended wordplay^^)
ur signature says "sometimes i talk with bots" + u tell crash to show you her boobs
